Answer:
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism.
Explanation:
The correct answer is B. In order for a society to be stable it must have access to a sustainable supply of resources.
By accessing sustainable supply of resources it enables the stability of a society.
Resources is termed as the supply or source from where benefit is being produced. Resources can be classified as non renewable and renewable ones.
Resources can be categorised as potential and actual depending on the level of use and development.
There are three characteristics of resources which include potential of consumption, limited availability and utility.
Answer:
If the chimpanzee’s zygote has 48 chromosomes, one would expect to find 24 chromosomes in a chimpanzee’s egg.
Explanation:
In a living organism, somatic cells are diploid and possess the full chromosome load, while gametes -sex cells- possess half of the total chromosomes, they are haploid.
The zygote of any organism that reproduces sexually results from the union of a male gamete and a female gamete, so its chromosome load is complete.
<em>This means that if the chimpanzee has 48 chromosomes in its cells, the female sex cell - the egg - has 24 chromosomes.</em>

Answer;
High-energy electrons pump hydrogen ions against the concentration gradient.
Explanation;
-The electron transport chain sets up a proton concentration gradient across the inner mitochondrial membrane, with more protons outside the membrane.
-As a result of this gradient, the protons are waiting to get across the membrane. This happens through the transmembrane protein ATP synthase, which uses the energy moving protons through its pore to add a phosphate to ADP, thus producing ATP.
